Application filed January 29, 1912. Serial No. 674,000.

To all whom it may concern:

Be it known that 1, JOHN H.

Another object of my invention is the provision of a fire-arm constructed to preserve the neat and attractive appearance of the same.

Another object of my invention is the assembling of the operating parts of a firearm in a manner to produce quick, positive and safe action in firing.

With these and other objects in view I will proceed to describe my invention with reference to the accompanying drawings forming a part hereof.

Fig. 23 is a detailed view of a latch for securing. the .closurefor the cartridge box in the closed position. Y i Fig. 24 is a detailed perspective view of the end of the barrel illus'tratingthe slide projection 9 having an interiorly threaded perforation 10 therein, while the part 8, of

the receiver, is provided with a lug 12, adapted to entera slot 13 formed in the part 7 of the receiver. The rear portion of the part 7 of the receiver, is provided with a dowel-pin 14, adapted to enter an opening 15'formed in the rear end of the part 8 of the receiver. After the dowelepin has been inserted in the opening 15, the lug 12, of the part8 of the receiver may be caused to enter the slot 13 in the part 7 of the receiver. After the stock 5 and barrel 6 have been in thismanner connected together, a threaded extremity 11 of a rod 17, may be caused to enter the perforation 10, and engage the lug '12. Consequently, by tightening this rod 17 its threaded extremity will move the part 8 of the receiver rearwardly, causing the latter to tightly engage the shoulder 18, withwhich the part 7, of the receiver is provided,i and the dowel-pin 14 to enter the perforation 15, with which the rear extremity of the part 8 of the receiver is provided.

In this manner the stock 5-and barrel 6 of the gun maybe firmly andrigidly connected 2 together.

Attention is here called to the fact that the parts 7 and8 of the receiver are formed of-integral pieces of material and by virtue of their. connection with each other the possibility of gas, resulting from the explosion on burstingof a shell, is prevented from escaping from the receiver in a rearward 'direction, and injuring the operator of the detailed view of the safety ceiver, is at right angles to the length of the fire-arm. Consequently, any gas escaping.

from the receiver, due to the bursting of a cartridge, must escape therefrom through the joint of the two parts of the receiver, laterally to the length of the fire-arm.

On the interior of the receiver formed by the parts 7 and 8, I arrange a slidably mounted breech-block21, which is operated by means of a slide-bar 22, having separated arms 23 and 24,which merge into each other at a point 25 and are connected with a handle 26, bymeans of which the slide-bar 22 is operated, which'in turn operates the breechblock 21. The arms 23 a'nd24 of the slidebar 22 are respectively provided with sectorshaped sockets 27, which sockets receive wheels 28 of eccentric cam levers'29 and 30,

the position of the cam levers 29, shown in Fig. 14. After the cam levers 29 and 30 have been moved or turned upon their pivots to cause their wheel-shaped extremities 28 to turn in the sockets 27 until they occupy a position similar to that shown in Fig. 5, it will be impossible to disconnect the cam levers from the arms 23 and 24 of the slidebar 22. The action of the arms 23 and 24 of the slide bar 22 upon these cam levers 29 and 30 results in operating the breech-block 21 to cause the latter'to move forwardly and rearwardly and at the same time results in operating the mechanism of the breech-block 21 for cocking the same.

In Fig. 3, the'breech-blocl; 21 and its parts are shown in a position set to fire the fire arm. And in this position the operation in firing is as follows :By pulling rearwardly upon a trigger 33, which is pivoted as shown at 34, an extension 35 is caused to is released and a spiralspring-44 permitted to act upon the same tomove the said firing pin forwardly with sufiicient force to ex plode or burst the primer of a cartridge 45, in the barrel 6, of the fire-arm.

provided, the said cam levers 29 and 30 at the same time, being causedto turn upon their pivots rearwardly, resulting in operating the cam lever 29 to cause its cam sur face 46 to act upon a pin 47 mounted in the breech-block 21 for protruding the said pin forwardly into engagement with the barrel 6 of the gun at a point 58, which results in moving the breech-block 21 rearwardly. Of course, the rearward movement of the slide-bar 22 is normally suflicient to move the breech-block rearwardly after the fire-arm has been fired, but since this rearward movementof the breech-block 21, results in extracting the shell, in a manner which will be hereinafter explained, the cam lever 29 acting upon the forward extremity ofthe receiver chamber through the medium of the pin 47, serves as a lever or leverage for accomplishing the easy extraction of tight shells from the barrel of the fire-arm.

The forward extremity of the breechblock 21 is provided with a cut out portion. 48, in which is pivoted a gripping dog 49 as shown at 50, the said dog having a tooth 51, which is adapted to engage the rim 52 of a cartridge for extracting the-latter from the barrel of the fire-arm. This gripping dog 49 is acted upon by means of a spring 53, to cause its tooth 51 to engage the rim 52 of the cartridge. This tooth 51 of the dog 49 engages the rim of the cartridge on one side, while the rim of the cartridge is engaged on the opposite side by an ejector,

pin 54, normally held in a retracted position by means of a spiral spring 55, which is interposed between the head 56, with which the rear of the pin 54 is provided, and a collar57, through which the said pin passes. By virtue of the gripping dog 49. the rim 52 of the cartridge will be engaged bythe same when the breech-block is in the position shown in Fig. 3 and consequently when the breech-block is moved rearwardly the shell will be extracted from the barrel 7 and carried rearwardly with the breechblock and will be ejected from the receiver in a manner which willlater be described. When the slide-bar 22 is operated by means of its handle 26 to carry the breech-block 21 rearwardly. the cam lever 29:is caused to turn upon its pivot in the direction of the arrow, Fig. l4;whereby the cam extremity 46 of the cam lever 29 is caused to act upon the pin 47 to move the latter forwardly into engagement with the barrel of the gun at the point 58 and as a result, the said pin acts'upon the barrel to form an additional leverage for assisting the breech-block 21 in its rearward movement to extract the tight or swollen shells from the barrel of the fire-arm as heretofore explained.

During the time that the cam lever is beingcaused to turn upon its pivot, in the direction of the arrow indicated in Fig. 14,

' the lever 301s also caused to turn upon its pivot in the same direction, or in the direction of the arrow indicated in Fig. 10, under the influence of the arm 24 of the slide-bar 22, which arm.is connected with the said lever 30 in the manner heretofore described. The turning of the lever 30 upon its pivot in, the direction of the arrow indicated in Fig. 10 results in. placing the spring 44 under tension, due to the rearward movement of the firing pin 43 independent of the rearward movement of the breech-block 21. This rearward movement of the firing pin 43, is accomplished by virtue of the following mechanism :slidably mounted in a chamber .59, in the breechblock 21. is a plunger 60, having a head 61 which engages the. collar or head 42 of the firing pin 43 in the man. This plunger 60 is connected with the cam lever 30 by means of a link 62, which is pivotally connected with the said cam lever 30, eccentric of the pivot of the latter, as shown at 63. The opposite extremity of the said link 62 is connected with the plunger 60 by means of a dowelpin or projection 64, with which the said link is provided, the said dowel-pin being inserted in a slot .4 formed in the plunger 60. Nowby virtue of the foregoing connections it may be seen that the rearward movement of the slide-bar 22 acts upon the cam lever 30 which in turn acts upon the firing pin 43, for cocking the fire-arm. or in other words. to place the firing pin 43 under the tension of the spring44, whereby as soon as the firing pin has been released. the spring will act upon the same to fire the fire-arm.- It must be noted that the iring-pin 43-is slidably mounted upon a. pin. A which is stationarily secured to the breech-block 21 by means of a pin which passes through. the rear extremity of the said pin A and enters the breech-block 21 and that this pin A. is provided with a shoulder 72 which forms a stop for'one extremity of the spring 44, (see Fig. 9) where by the said spring may be placed under tension by the rearward movement of the firing pin 43. The rearward movement of the breech-block 21 musthave been completed and the block started on its forward movement in order to eject the shell. and the. breech-block must have been moved forwardly adjacent the breech of the fire-arm before the'firingpin 43 can be released to fire the gun. I

Attention is'here called to the fact that when the breech-block 21 is adjacent the breech of thegun, or in position to fire the latter, as represented in Fig. 3, the cam levers 29 and 30 will occupy depending'po- 'sitions with respect to the breech-block 21 or positions indicated by the dotted lines in Fig. 3, whereby the breech-block 21 is supported in theraised positionwith the rear extremity ofthe breech-block 21 in engagement with the breech shoulder 65, by virtue of cam levers 29and 30 supported by the through the medium of the cam levers 29 and 30, to move the said breech block rearwardly. As soon as thebreech-block 21.

starts rearwardly it engages the inclined surface 68 of the receiver and as a result tilts the forward extremity of, the breechblock upwardly, and when the breech-block 21 has reached its limit of rearward movement the cooking operation will have been completed, by virtue of the mechanism heretofore explained and the shoulder 41, of the sear 39, allowed to engage the collar 42 of the firing pin, whereby the firing-pin will be held in position against the tension of the spring 44 until released in the manner which will be later described. Before the breech-block 21 has reached its rearward limit of movement, a pin 69 slidably mounted in a chamber 70 formed in the breechblock 21 will have engaged the shoulder 18 of the receiver and the completion of the rearward movement of the breech-block 21 will result in placing a spring 72 under tension, which acts upon a pin 73 havingan enlarged ball-shaped head 74 engaging the head 56 of the ejecting pin 54. But since the rim of the shell is held in a recess 75in the forward extremity of the breech-block 21, by the tooth 51, of the extractor dog 49, the said shell forms a stop for the ejector pin 54, which in-turn holds the pin 73 against movement and causes the spring 72 to be maintained under tension and prevented from acting to eject the shell until after the latter has been released by the tooth 51 of the extractor dog 49. Therefore, when the breech-block 21 has reached its limit of rearturn .the dog- 49 upon its-'pivot50, against the tension ;of the spring 53, to release its tooth 51 from engagement with the rim '52 of the shell and as soonas this tooth 51 has been released, the spring 72 will expand and act upon the pin 73, which in turn acts upon the ejector pin 54 toeject the shell through an ejector opening .79formed .in the side of the part 8 .of the receiver,v(see Figs. 1 and 4). As soon as the pin 76 of the dog 49, has been reelased from the recess 77, the pin will be caused to move into the dog against the tension of its spring and the spring.53 will act upon the dog to cause the latter to assume its normal position.

When the breech-block 21 reaches its forward limit of movement, the cam levers 29 and 30 will be turned in the direction opposite the arrows indicated in Figs. 14 and 10 respectively, and as a result the cam lever 30 will act upon the link 62to move the plunger 60 against the tension of a spring 80 and when the breech-block 21 has reached its limit of forward movement the reduced extremity 81, ofthe-plunger- 60 will have been brought adjacent an opening 82 in the bottom of the breech block 21, whereupon a projection 83, with which the forward extremity of, the sear 39 is provided will be permitted to move inwardly against the tension of a spring 84 interposed between the sear and the breech-block, when the projection 38, of the sear is acted upon for firing the fire-arm, whereby the shoulder 41, of the sear 39 will be released from the shoulder or collar 42 with which the firing pin 43 is provided. When the breechblock 21 is moving rearwardly, the plunger 60 will also move-rearwardly independently of the breech-block 21, by Virtue of the connections hereinafter explained, whereby the reduced extremity 81,015 the said plunger will be caused to move out of register with the opening 82 and this opening will be closed by a tubular sear lock 85, which receives one extremity of the spring ,80, and follows after the plunger 60 under the influence of the spring 80. As soon as this sear-lock 85 comes into register with the opening 82,. the said openingwill: beclosed against the entrance of the projection 83 of the sear 39 and as a result will prevent the turning of the sear 39 upon'its pivot 40,

and consequently, the sear 39 will be locked against accidental disengagement of. its shoulder 41 from the shoulder or collar 42, of the firing pin 43, thus obviating the possibility of theogun being accidentally discharged. The sear-lock 85 will not totally uncover the opening 82 to permit the entrance of the projection 83 of the sear 39 until the breech-block 21 has reached its limit of forward movement, and occupies the proper position for discharging the fire arm.

When the breech-block 21 and its parts are in proper relative position for discharging the fire-arm, the parts may be locked against operation for firing the gun by means of a locking member 86 (see F ig. 19) having a slot therein, which receives the pivot pin 34 of the trigger 33, the forward extremity of the said member being provided with a lug 88 extending at right angles thereto and adapted to be passed under an extension 89, with which the trigger 33 is provided. Therefore, when the lug 88 has been moved to a position beneath the extension 89 of the trigger 33, the trigger 33 will be held against turning upon its pivot 34 and as a result the member 37 cannot be actuated for operating the sear 39 to release the firing pin. The locking member 86 is provided with a pin having an operating member 90 which passes through a slot 91 formed in the part 7 of the receiver adjacent the trigger guard 92.

I will now proceed to describe the mechanism employed for locking the breech-bl0ck 21 in position to fire the gun. On the opposite sides of the part 7, of the receiver, I mount a slide-bar locking device 93, (see Figs. 7 and 22) which consists of a bar arranged parallel or in alinement with the arm of the slide bar 22. This bar or locking device 93 is pivotally mounted on the part 7 of the receiver, as shown at 94, and is provided with a triangular shaped right angular projection 95, which normally occupies a position in a cam-notch 96 formed in an inertia block 97 When this projection 95 is received in the notch 96 of the inertia block 97, the bar 93 is caused to as sume the full line position represented in Fig. 7 ,-by virtue of a spring 98, acting upon the said bar 93, whereby the forward extremity of the bar 93 occupies a position directly in the path of the arm 23 and as a result the slide-bar 22 will be prevented from moving rearwardly by virtue of the engagement of its arm 23 with the locking device 93. The bar 23 is provided with a shoulder 94 adapted to be engaged by the forward extremity of the bar or locking devices 93. Now, whenever, the fire-arm is discharged, the recoil of the same will act upon the inertia block 97 to slide or jar the latter forwardly, whereby the notch 96, with which the said inertia block is provided is caused to move forwardly beyond the projection 95 of the bar 93 and as the projection 95, of the bar 93, rides out of the notch 96, the said bar 93 is tilted upon its pivot 94 to disengage its forward extremity from the shoulder with which the arm 23 is provided, for leaving the slide-bar 22 free to move rearwardly and carry the breech-block 21 therewith. Attention is here called to the fact that the inertia block 97 is provided with a longitudinal slot 99 through which a pin 100 is passed. The slot 99, of the said inertia block 97 serves to permit the inertia block to slide back: wardly and forwardly upon the said pin 100. After the arm23 of the slide bar 22 has been released in the above described manner, and after the slide-bar 22 has been operated to carry the breech-block 21, rearwardly, the said breech-block will come into engagement with a member 101, having a projection 102 which is pivoted to the rear extremity of the inertia block by means of a pivot pin 103. The further movement of the breech-block 21 will result in sliding the inertia block 97 rearwardly and the pivoted member 101 will engage the shoulder 18 with which the part 7 of the receiver is provided and will be caused to be depressed against the tension of a spring 104, whereby the said member will be received in an opening' 105 with which the shoulder 18 is provided and a projection 106 of the said member 101, will engage the wall of the opening 105, as shown at 107, under the influence of the spring 104 acting upon the said member 101. In this manner the inertia block 97 will be caused to move rearwardly until its notch 96 is brought into register with the projection 95 of the bar 93, whereby the said bar will be allowed to turn on its pivot 94 under the influence of its own weight to cause its forward extremity to assume the full line position or the position in the path of the arm 23 of the bar 22 to prevent the latter from being moved rearwardly. Whenever it is desired to release the bar 93 from engagement with the arm 23 for unlocking the fire-arm to permit the breech-block 21 to move rearwardly, the said bar may be tilted out of engagement with the arm 23 by moving a in 108 upwardly in the slot 109 (see Fig. 5 This pin is secured to the bar 93 and protrudes through the slot 109 in the part 7 of the receiver, adjacent the trigger guard 92.

Attention is here called to the fact that when the slide-bar 22 is moved rearwardly for causing the breech-block 21 to move to the rear position, heels 108 with which the cam levers 29 and 30 are respectively provided are caused to engage the top wall of the part 8 of the receiver and force the breech-block 21 downwardly to release its rear extremity from the shoulder 65, so that the said breech-block may be moved rearwardly.

The breech-block 21 slides between the top wall of the part 8 of the receiver and the top tr: part 7 the, receiver, the said breech-blo'ck snugly fitting between the two parts to prevent it from moving laterally in any direction.

In the part 7 of the receiver, I arrange parallel spaced partitions or walls, 109, a space 110 beingleft between each of the sald partitions or walls and the sides of the part 8-. of; the receiver for the reception of the arms 23 and 24 of the slide-bar 22. n The partitions or walls 109, also formopposite sides of a cartridge box 113, the top of each partition orwall being provided with an inwardly extending flange 114 which serves to close the top of the cartridge box 113 sufliciently to prevent the lateral removal of a cartridge from the said box. When the breech block 21 is moved forw'ardlyQthe loweredge 121 of its forward extremity engages the rim 52 of a cartridge and moves the cartridge longitudinally to cause the'latter to passthrough an enlarged opening 122'inthe cartridge box and enter the barrel ofthe fire-arm. I I

The cartridges in the cartridge box 113 are supported in position'so that one will be removed therefrom each time the breechblock 21 is moved from its rear position to its forward position. The cartridges are supported in this position by means of a cartridge shelf. 115 upon which the cartridges rest. This shelf is supported by means of an arm 116 pivotally connected at one extremity with the member 115 as shown at 117, while its opposite extremity is pivotally connected as shown at 118. The pivot of arm serves as the pivot pin or hinge for a closure 119 of the cartridge box 113; The arm 116 is actuated by means of a spring 120 to cause the said arm to move the cartridge shelf115 upwardly and carry the cartridges therewith, to a position where one of them will be removed from the cartridge box and inserted in the barrel of the fire-arm at eachforward movement of the breech-block 21. The forward extremity of the closure 119 for the cartridge box 113 is pivoted upon the pin 118 cause its projection 126 to interlock with 'the'hook 127 ofthe closure 119 by means of e spring 128; By virtue of this construction wheneverthe part 129 of the dog 124' is pressed upwardly its projection 126 will be caused to be disengaged from the h ook 127 and allow the closure 119 .of the cartridge box'to move to the open position, indicated in Fig. 17, under the influence of the spring 120. The trigger guard92 serves as a shield or guard' 'for the dog 124-as well as'for the v of the fire-arm, due to the fact that the lug 38 of thefsear' 39 is always disengaged from the member 37'when the breech-block 21 is in any position other than its forward position. As heretofore explained the sear 39 is actuated by the trigger'33 through the medium of the member 37 to fire the firearm, and consequently when the lug 38 of the sear 39 is disengaged from the member 37, the gun cannot befired.

When the lug 38 of the sear 39 is in engagement with the member 37, the slide-bar 22 must have been moved forwardly far enough to permit the locking bar 93 to engage the shoulder 94 of the arm 23 and as a result the fire-arm is maintained in the locked position for firing. r

Whenever the two parts 7 and 8 of the receiver are disconnected the slide-bar 22 will "be heldin position by a spring actuated pin 134, which engages a notch 135 formed in the inner side of the arm 24 of the slide-bar 22. This pin 134is mounted in the lug or projection 12, formed upon the part 8 of the receiver and is held'in an inoperative'or withdrawn position by means of the part 7 of the receiver, which engages the said pin when the two parts of the receiver are connected and pushes the pin 134 inwardly against the tension of its spring so as to permit the notch 135 in the arm 24 to clear the pin- 134 during the movement of the slide-bar 22. This pin 134 is forced outwardly by means of its spring into the notch 135 when the parts 7 and 8 of the receiver are disconnected and, as a result holds the slide-bar. 22 in position, which in turnsupports the" breech-block 21 in position in the part 8 of the receiver.

In order to cover up the arms 23 and 24 of the slide-bar 22, between the handle of the latter and the receiver of the fire-arm, I provide a cover 136, which I interpose between the receiver and the handle of the slide-bar 22. "This cover 136 fits over the arms 23 and 24 of the slide-bar, with its cap 137, adjacent the receiver ofthe fire-arm,

while the opposite extremity of the cover is adapted totelescope with the handle26 when the latter is drawn rearwardly for cooking the fire-arm. The forward extrem- -ity of the cover 136 protrudes slightly into the handle 26, which' forms a support for the forward extremity of the cover, while the opposite extremity of the cover is supported on the rod 17 by means of a spring actuated pin 139, which normally closes the slot 138 against the passage of the rod 17 from the said slot.

In the foregoing description I have passed over mentioning certain specific features in connection with the breech-block and I will now describe these features. The firing pin 43 is mounted in a chamber 140. This chamber is slightly enlarged at its rear extremity as shown at 141 to permit the movement of the enlarged head 42, of the firing pin 43 therein. The forward extremity of the firing pin 43 is provided with a reduced part 142, which passes through an opening 143 in the forward extremity of the breech-block 21. The firing-pin 43 is hollow and within the hollow the spring 44 is arranged. The inner portion of the pin A is inserted through the spirals of the spring, and forms a guide for the spring when the latter is being placed under tension. The pin 3, which holds the rod A in the stationary position, enters the top of the breech-block 21 and the side of the enlarged head 42 of the firing pin 43 is cut away as shown at 144 (see Fig. 10), to permit a maximum degree of rearward movement of the firing pin 43 upon the pin A.

The pin 69 is tubular whereby a maximum length of the spring 72 is obtained and the pin 69 is prevented from being extended its full length beyond the breech-block 21 when the spring 7 2 is permitted to expand.

Attention is here called to the fact that the cam extremities of the cam levers 29 and 30 are beveled off as shown at 145 to prevent the cam levers from hanging against the walls of the receiver when the said cam levers are turned.

By referring to Fig. 6, it may be noted that the breech-block 21 normally occupies a position directly on top of the arms 23 and of the slide-bar 22 and that as the slide-bar 22 is moved forwardly the cam levers 29 and 30 furnish a maximum degree of leverage for firmly and rigidly holding the breech-block in its forward positlon or in the position to fire the gun. These cam arms 29 and 30 furnish or afford a maximum degree of leverage, resulting in forcing the firing pin 43 to the cooked position, a ainst the influence of the spring 44, with great ease.
